Energizer® 51R-AGM Automotive Battery
Energizer® 51R-AGM Automotive Battery

Starts fast when the temperature drops

Engines need more power to start in cold weather. This gradually drains the battery of its charge, which is why it always seems like batteries fail during winter. Energizer® AGM batteries are precision engineered to last up to 2 times as long as standard flooded batteries in cold climates by delivering more starting power and recharging faster.

Reliable power for today’s vehicles

Today’s vehicles have more than 150 electrical devices to keep you safe and comfortable, 7 times the number of 20 years ago. Accessories such as backup cameras, navigation systems, and heated seats all contribute to the electrical demand on a battery. Energizer® AGM batteries are precision engineered to last up to 2 times as long as standard flooded batteries while powering all of your electrical needs.

Tested in real world conditions

Today’s driving conditions wear down a battery. Short trips and stop-and-go traffic do not allow the battery to adequately recharge, while the condition of many roads causes batteries to vibrate, loosening connections and hurting performance. Energizer® AGM batteries are precision engineered to last up to 2 times as long as standard flooded batteries in real-world conditions by recharging faster and resisting deterioration from external factors.

Tomorrow’s battery, available today

More and more automotive manufacturers are adopting Start-Stop technology to meet fuel economy and emissions standards. Start-Stop shuts off the engine during idle, placing more electrical demand on the battery. Only AGM batteries are precision engineered to last up to 2 times as long as standard flooded batteries when supporting Start-Stop technology.
